Stomach ulcers

Stomach ulcers occur in the lining of your stomach. Although they are common and can be treated, it's important to be aware of the symptoms and get diagnosed early. If left untreated, stomach ulcers can lead to more serious complications.

What are stomach ulcers?

Stomach ulcers are open, inflamed sores in the lining of your stomach. They are also known as gastric ulcers or peptic ulcers. You can also get ulcers in the upper part of your small intestine — these are known as duodenal ulcers.

How are stomach ulcers diagnosed?

Stomach ulcers are most commonly diagnosed by endoscopy — using a flexible tube with a tiny camera that’s passed into your mouth and down to your stomach. This procedure is done under general anaesthetic.

You’re also likely to have tests to check for Helicobacter pylori infection. Usually this involves a breath test, or a test of the stomach lining during endoscopy.
